No Main class found in NetBeans

Question

I have been working on an assignment for my class in programming. I am working with NetBeans. I finished my project and it worked fine. I am getting a message that says "No main class found" when I try to run it. Here is some of the code with the main:

package luisrp3; import java.io.FileNotFoundException; import java.io.PrintStream;  public class LuisRp3 {  public static void main(String[] args) throws FileNotFoundException  {      java.io.File newFile = new java.io.File("LuisRamosp4.txt");      if (newFile.exists()) {         newFile.delete();     }      System.setOut(new PrintStream(newFile));      Guitar guitar = new Guitar();  

I posted this before but had a couple issues. i have fixed the others and now have just this one remaining. Any advice will be greatly appreciated.

Answer 1

1. Right click on your Project in the project explorer
2. Click on properties
3. Click on Run
4. Make sure your Main Class is the one you want to be the entry point. (Make sure to use the fully qualified name i.e. mypackage.MyClass)
5. Click OK.
6. Run Project :)

If you just want to run the file, right click on the class from the package explorer, and click Run File, or (Alt + R, F), or (Shift + F6)

Answer 2

Also, for others out there with a slightly different problem where Netbeans will not find the class when you want when doing a browse from "main classes dialog window".

It could be that your main method does have the proper signature. In my case I forgot the args.

example: public static void main(String[] args)

The modifiers public and static can be written in either order (public static or static public), but the convention is to use public static as shown above.

Args: You can name the argument anything you want, but most programmers choose "args" or "argv".
